That’s how dual motor Teslas work - the front wheels are geared for higher speeds, and more power is shifted towards those as you go faster. No gear-shifting required. Yep. Alternatively, the Porsche Taycan has an 2-speed transmission gearbox (cf. https://www.caranddriver.com/news/a28903274/porsche-taycan-t... ). I don't think gearboxes ar…

I don't expect stickshift EVs to be common either, but still I think it's surprising that no one has made a non-luxury-car EV that isn't direct drive. Manual transmissions seem like a pretty mature technology at this point. For any car company that already makes a manual transmission car it would be easy to do. They might change the design a little (maybe 3 speeds instead of 5, and use sturdier gears and different ra…

Yeah, I'd have thought a DC motor plus a two-speed transmission would be a no-brainer for the budget end of the market (at least until high power AC drives come down a bit) but maybe not.

What batteries are you using for the RX-8?

In Europe, manual transmissions are generally preferred because they're cheaper, not because they're more fun to drive.

I have a friend who dropped a turbocharged engine out of an old 80s BMW into an RX-8. He ended up having to cut a hole in the firewall and completely redesigning the rack and pinion because the old rack would have gone through the middle of the larger BMW engine. He kept the original gearbox and was always worried the low revving high torque BMW engine was going to murder it. :P

Thankfully I don't have that problem. The Netgain motor is pretty big as motors go and it'll be close to the power steering unit, but still I think I've got enough room there. Most of the work so far has been making battery boxes. I've got one under each rear seat where the gas tank used to be, one in the front down low where the radiator used to be, a smaller one above it, and another that goes over the motor (which…

How do you plan to do heating? Even if it doesn't get cold where you live, but you'll still need heat (and maybe A/C) to avoid fogging the windshield when it's humid. An electric heater, powered by the same batteries?

Subaru CVTs already have essentially this feature. The transmission doesn't have gears (duh, it's continuously variable) but it still has the ability to manually shift to predefined ratios.

Their CVTs also use these simulated gears during normal automatic driving, presumably just to make it feel more like a traditional automatic (which it mostly does, to my untrained senses). Apparently this is important to the car-buying market, although I don’t understand why.

Car reviewers love to complain about how a CVT lets the engine rev up to high RPMs and just stay there the whole time you're accelerating. Which is of course the entire point, but some people apparently prefer that their car spend lots of time at suboptimal RPMs, probably so that they don't have to break the habit of flooring it unnecessarily.

At least here in Poland you can only take the exam in the car provided by the testing centre, you can't have the exam in your own car(with some exceptions like when you need to have a car adjusted to your disabilities)

I believe that's the case all over Europe. That the US apparently or supposedly allows taking a car driver's license exam in your private car is.. extremely surprising.

It's not in UK(I realize it's not part of the EU any more, but even when it was it was the same). You take the exam in your own car or a car provided by the training school. The exam centres don't have cars.

Somebody put that in an early electric performance car. You actually had to shift, and got audio effects, but it was just software emulating gears. It was laughed at in the automotive press.

People don't like fake.

Sure we do, we just don’t like bad fakes.

(Bad is subjective, but the point remains)

I wonder what torque looks like at 0 rpm. I thought that was peak? But If it’s bad maybe a torque converter would be useful?

Electric motors "torque ripple" at low RPMs (well, at all RPMs, but it is most noticeable at lower RPMs), which can cause motor "cogging". Cogging is either a complete stall, or really jerky behavior that feels pretty close to what an ICE is like at very low RPMs. * There are different motor designs out there that alter power delivery for situations where very low-RPM torque is required. As with most design decisions…

OT: Wow I somehow feared a Flash animation intro when loading the main site newdelorean.com. Probably due to the old-school feeling of the logo and a progress bar.

Those days are thankfully done since Flash Player refuses to play web content after Jan 1 2021.
